London chef Ollie Dabbous has claimed that he will retire from the kitchen in 10 years' time because the job is so intense.
The chef, 33, claims to get by on just four hours' sleep a night.
He won his first Michelin star for Dabbous restaurant in Fitzrovia last year and opened a second called Barnyard in March.
He told the Times: "I'm enjoying it for now. But while to begin with I thought I would be doing for the rest of my life, now I view it as more a sporting career.
"The way the bar's been set with all the reviews and expectation levels, I can't let things plateau or drift. We need to keep up this level of intensity and execution and I've got to do it while I am still physically able."
